TITLE TOUGHENED POLYOXYMETHYLENE COMPOSITIONS Polyoxymethylene compositions having 15-40 wt. % thermoplastic polyurethane, where the polyurethane has a glass transition of lower than -15.degree.C, the polyoxymethylene has a molecular weight of 20,000-100,000, and the polyurethane is dispersed in the polyoxymethylene as small particles show extraordinary toughness as measured by notched Izod. |
